Description

Technical Field

[0001] This utility model relates to a storage tank, and more specifically, to a liquid wax storage tank. Background Technology

[0002] Traditional emulsion explosive production processes use solid composite wax and drummed emulsifiers as raw materials. The operation relies on manual addition of these oil-phase raw materials and manual calculation of the weight of each material according to process ratios. This results in low levels of industrial automation and precise batching. To improve production efficiency, most manufacturers are now using liquid wax as a raw material. The liquid wax and emulsifier are stored in separate tanks and automated through pipelines, valves, and sensors for batching.

[0003] Wax is typically solid at room temperature, so liquid wax requires continuous heating of the pipeline during transport to maintain a certain temperature and prevent solidification. In current production, heating is usually achieved by installing coils on the outer wall of the pipeline. However, this heating method results in insufficient contact between the coils and the pipeline surface, leading to low heat exchange efficiency and easy condensation on the pipeline surface, which can cause rust over time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a liquid wax storage tank that ensures sufficient contact, high heat exchange efficiency, and prevents the accumulation of condensate.

[0005] The technical solution of this utility model is implemented as follows: A liquid wax storage tank includes a tank body, a feed pipe connected to an external feeding device on one side of the tank body, and a discharge pipe connected to the lower end near the end of one side of the tank body; the feed pipe is conductively connected to the upper end near the end of the tank body; an insulation jacket pipe is provided outside the feed pipe, a high-temperature steam pipe is connected to the front end of the insulation jacket pipe, and an exhaust pipe is connected to the end of the insulation jacket pipe; a high-pressure purging pipe is connected to the high-temperature steam pipe through a tee, and a pressurization component is provided inside the upper end near the end of the insulation jacket pipe.

[0006] In the aforementioned liquid wax storage tank, the pressurization component includes an installation pipe with a flange connected to an insulated jacket pipe, and a baffle is provided inside the installation pipe. The baffle has a plurality of pressurization holes evenly distributed in a ring along the circumference.

[0007] In the aforementioned liquid wax storage tank, the pressure boosting orifice is funnel-shaped and gradually narrows along the airflow direction.

[0008] In the aforementioned liquid wax storage tank, a drain valve is provided on the exhaust pipe; a bypass pipe is provided on the exhaust pipe at the front end of the drain valve, and a manual quick-opening valve is provided on the bypass pipe.

[0009] In the aforementioned liquid wax storage tank, a first pneumatic valve and a first manual valve are sequentially provided on the high-temperature steam pipe, and a second pneumatic valve and a second manual valve are sequentially provided on the high-pressure purging pipe.

[0010] With the above-described structure, this invention forms a hot steam channel through the insulated jacketed tube, allowing high-temperature steam to directly contact the surface of the feed pipe. This effectively improves heat exchange efficiency and ensures the efficient transport of liquid wax within the feed pipe. Simultaneously, after feeding, a high-pressure blowing pipe can be used to purge the insulated jacketed tube with high-pressure airflow. This high-pressure airflow removes the condensate generated during heating, keeping both the insulated jacketed tube and the feed pipe dry and reducing the possibility of rust.

[0017] See Figure 1-4 As shown, this utility model discloses a liquid wax storage tank, comprising a tank body 1. A feed pipe 2, connected to an external feeding device, is attached to one side of the tank body 1, and a discharge pipe 3 is connected to the lower end near the end of one side of the tank body 1. The feed pipe 2 is conductively connected to the upper end near the end of the tank body 1. An insulated jacketed pipe 4 is provided outside the feed pipe 2. A high-temperature steam pipe 5 is connected to the front end of the insulated jacketed pipe 4, and an exhaust pipe 6 is connected to the end of the insulated jacketed pipe 4. A high-pressure purging pipe 7 is connected to the high-temperature steam pipe 5 via a tee. A pressurization component 8 is provided inside the upper end near the end of the insulated jacketed pipe 4. The high-temperature steam pipe is connected to an external steam delivery component, and the high-pressure purging pipe is connected to an external high-pressure gas source.

[0018] Heating coils and corresponding temperature sensors are installed on the outer wall of the tank to maintain a suitable storage temperature inside the tank. This is a common existing technology used in the storage of liquid wax and is common knowledge to those skilled in the art, so it will not be elaborated here.

[0019] The insulated jacketed tube forms a hot steam channel, allowing high-temperature steam to directly contact the surface of the feed pipe, effectively improving heat exchange efficiency and ensuring the efficient delivery of liquid wax within the feed pipe. Simultaneously, after feeding, a high-pressure purging pipe can be used to blow out the high-pressure airflow entering the insulated jacketed tube, removing the condensate generated during heating and keeping both the insulated jacketed tube and the feed pipe dry, reducing the possibility of rust.

[0020] In this embodiment, preferably, the pressurization assembly 8 includes a mounting pipe 8a connected to the insulation jacket pipe 4 by a flange. A baffle 8b is provided inside the mounting pipe 8a, and several pressurization holes 8c are evenly distributed in a ring along the circumference of the baffle 8b. The pressurization holes reduce the flow area, increasing the airflow pressure and improving the flow velocity. The mounting pipe is connected to the insulation jacket pipe by a flange, facilitating disassembly and replacement. Pressurization assemblies with pressurization holes of different diameters can be replaced according to actual needs.

[0021] More preferably, the pressure boosting orifice 8c is funnel-shaped and gradually narrows along the airflow direction. When the airflow passes through the funnel-shaped, gradually narrowing pressure boosting orifice, the air pressure can be further increased.

[0022] In this embodiment, preferably, a drain valve 9 is provided on the exhaust pipe 6. The drain valve's features enable automatic opening and closing, simplifying operation and making it convenient to use.

[0023] A bypass pipe 10 is provided on the exhaust pipe 6 at the front end of the steam trap 9, and a manual quick-opening valve 11 is provided on the bypass pipe 10. In the initial state, the steam trap pressure is low, and condensate cannot pass through the steam trap and thus accumulates in the front exhaust pipe. When high-pressure gas is used for purging, this part of the condensate is blown to the bypass pipe and discharged, so that high-temperature steam can pass directly through the steam trap when it is subsequently introduced.

[0024] In this embodiment, a first pneumatic valve 12 and a first manual valve 13 are sequentially installed on the high-temperature steam pipe 5, and a second pneumatic valve 14 and a second manual valve 15 are sequentially installed on the high-pressure purge pipe 7. Initially, the first and second manual valves are normally open. The first and second pneumatic valves work in conjunction with the high-pressure purge pipe and the high-temperature steam pipe, respectively, to prevent high-pressure gas from impacting the steam delivery components during high-pressure purge and to prevent steam from entering the high-pressure purge pipe and impacting the high-pressure gas source during temperature regulation. When the first or second pneumatic valve malfunctions, the corresponding first or second manual valve ensures the closure of the pipeline.

[0025] During operation, before connecting the feed pipe to an external material source for feeding, the first pneumatic valve is opened. The external steam delivery assembly inputs high-temperature steam into the insulated jacket pipe to preheat the feed pipe, while the heating coil preheats the tank body. After preheating for a certain period of time, the external material source delivers liquid wax into the feed pipe for feeding.

[0026] After feeding is completed, the first pneumatic valve is closed, and the second pneumatic valve is opened at the same time. The high-pressure gas source delivers high-pressure gas into the insulated jacket pipe for purging. The high-pressure gas carrying condensate is discharged from the exhaust pipe.

[0027] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
